COMPARATIVE EVALUATION OF PERFORMANCE AND CO2 EMISSIONS FROM DUAL FIRED POWER PLANTS IN GHANA Thesis 아주대학교 국제대학원 국제대학원 융합에너지학과 2020. 2 Master I804:41038-000000029435 http://dcoll.ajou.ac.kr:9080/dcollection/common/orgView/000000029435 Assessment Data Envelopment Analysis (DEA) Performance Electricity generation utilities in Ghana are the most focal point of attention ever since the country went into electricity supply crises. In other to meet demand there has been a sharp increase in thermal power generation. According to [1] the electricity supply industries is one of most complex technological and technical systems with several management and regulatory process and activities. The critical issue however with thermal generation is the type of fuel used as well as the environmental consequences in using different fuels for power generation. In light of this, assessing the performance of power plants is key to keeping them working efficiently and environmentally friendly for constant supply of electricity. Data Envelopment analysis (DEA) a Technical Efficiency performance assessment tool, was used to assess and compare performance of thermal power plants in Ghana by measuring and evaluating their overall Technical Efficiencies on CO2 emissions and electricity generation. This was done by placing emphasis on the most relevant inputs and output parameters. The study was therefore carried out to determine the most efficient power plant in the year 2018 based on the amount of electricity generated against CO2 emissions as desired outputs. The result showed that, KTPP and AMERI power plants were the most efficient power plants both having their relative technical efficiency score of 1 when CO2 Emission and generation were considered as desired output parameters.
